There is zero chance that Dodge and Chevy have real world reliability greater than makes like Toyota, Honda and Mazda.
They also play games like counting “problems” without a weight. Infotainment problem fixed in firmware and transmission problem both increment the count by 1?
It's very possible for Dodge and Chevy to have greater initial quality (meaning fewer reported problems) but worse real-world reliability than their Japanese counterparts. Dodge, for example, is notorious for using parts that wear down quickly. Also, Dodge and Chevy have more vehicles that target the low end of the market, where people are more likely to just accept small problems with the car as part of the cheap car experience.
